If that's not scary enough, the local news some years back had a story where the automotive news guy went to a test track where someone showed him how easy it was to hack into a vehicle's computer system with a laptop and the right hacking tools/software. To prove they got in, they activated the vehicle's brakes without the driver stepping down on the pedal. The idea that everything should have internet connectivity should also be tempered by the idea that insecure devices are a way for hackers to cause havoc, steal one's identity, etc. Sadly, nobody cares about privvacy concerns until after a data breach. At that point, the horse has already left the barn and it's too late for those already victimized.
Oh joy. So your expensive Tesla Model S can be immobilised by order of the state by way of a backdoor (which will also be used no doubt by criminals to invent the cyber carjacking).
Stop the planet, I want off.
